Why It Matters
When the CAS market becomes volatile, the price of derivatives can swing wildly, making it difficult for traders to lock in fair prices. VWAP is a benchmark that averages the price of a security over a period, weighted by volume, and is used to gauge a fair execution price. By applying VWAP to derivatives that expire on the same day as CAS, SEBI intends to smooth out price swings and provide a more reliable reference for traders. This can reduce the risk of sudden price gaps at expiry and improve overall market stability. For investors, a more stable expiry process means less uncertainty around the final settlement price of derivatives, which can influence hedging strategies and the cost of entering or exiting positions. **Update 06:27 PM IST:** Sebi reintroduces VWAP for derivatives expiry after CAS turns markets volatile
What Happened
SEBI announced that the VWAP mechanism will be reinstated for derivatives that expire on the same day as the Cash and Settlement (CAS) market. The decision follows a period when the CAS market experienced significant volatility, leading to sharp price swings in derivative contracts. The VWAP rule will apply to all listed equity derivatives that expire on the same day as the CAS market, ensuring that the final settlement price is calculated based on the volume‑weighted average price over the trading day. This change is intended to provide a more transparent and fair pricing benchmark for traders and investors, reducing the impact of sudden price movements at expiry.

Frequently Asked Questions
What is VWAP and why does it matter for derivatives expiry?
VWAP stands for Volume Weighted Average Price. It is the average price of a security over a period, weighted by the trading volume at each price level. For derivatives that expire on the same day as the cash market, VWAP provides a fair and transparent benchmark for the final settlement price, helping to reduce sudden price swings.
Will this change affect my ability to trade derivatives?
The rule applies to all equity derivatives that expire on the same day as the cash market. It does not restrict trading but sets a benchmark for the final settlement price, which may make expiry pricing more predictable.
Does this benefit or hurt hedgers using derivatives?
A more stable expiry price can reduce the risk of large price gaps, which is generally beneficial for hedgers who rely on predictable settlement prices.
How will brokers adapt to the new VWAP rule?
Brokers will need to ensure their systems can calculate VWAP accurately and provide clients with the benchmark price. This may involve updating trade execution algorithms and reporting tools.
Will the VWAP rule affect the liquidity of the derivatives market?
If more traders use VWAP as a reference, liquidity may become more concentrated around the VWAP price, potentially widening spreads at other price levels. Monitoring liquidity patterns will be important.
